Ashley Greene headed to her LA-area gym yesterday afternoon in sneakers and spandex and swapped t-shirts before leaving with a friend. The actress has been sticking to her routine for most of the Summer, fitting in workouts, attending red-carpet events, and dining out with friends. Ashley has done her share of traveling, as well, visiting her family in Florida and having some fun in NYC. She's remained single since her split from Joe Jonas, but might be moving in with someone soon. Kellan Lutz said he and Ashley may rent an apartment in NYC to share, though the pair are longtime friends rather than a romantic couple. Kellan didn't join Ashley as she teamed up with some of her fellow Twilight saga costars at Comic-Con just a few weeks ago to share an early look at the first Breaking Dawn installment, but he'll reunite with them again at this Sunday's Teen Choice Awards. Kellan, Ashley, Robert Pattinson, Kristen Stewart, Taylor Lautner, and several other members of the cast are expected to attend as they did last year.
